This is a nice USB 3.0 port multiplier and it works well in some applications. You really need to understand the limitations of such devices when using it with your computer and external devices. A port multiplier splits the communication rate and power from the USB port to allow it to be shared with the four ports on the hub. In the case of power, a USB 2.0 port can supply 500 milliamps of power and a USB 3.0 port can supply 900 milliamps that will be split 4 ways if you have four devices plugged in.

If your devices are self-powered by their own power supplies you should have no problems. Devices like printers, scanners and some USB Hard disk drives (With external power supplies) are examples of this. In my testing I used a USB powered hard disk drive (HDD) and three USB memory sticks. When I plugged in the port expander all four devices where present in my computer drive list then they disappeared one at a time by themselves and then the USB 3.0 port stopped working I had to disconnect the hub and reboot my computer to get the USB port on the computer active again.

In the example I used for testing, all four devices require power from the USB port to operate and as a result issues occurred. Low power can result in memory loss or the improper writing and reading of data. Using one of these devices or two worked but then it is not a fully functional port multiplier if the power requirements exceed the power capabilities of your computer's USB port like when I was trying to use 3 or 4 devices simultaneously. Had I used my example of a self-powered scanner, printer, a USB HDD with a power supply and a memory stick then all would have been working fine.

The unit is nicely designed and lightweight for portability weighing only 2 ¾ ounces.

My first problem is the size of this, this must be a desktop model, because it's too big for travel in a briefcase. They could have made it 1/4 the size. If you've used the Belkin USB 2.0 4-Port Ultra-Mini Hub you'll be surprised at it's size. This Sabrent 4 Port Portable USB 3.0 Hub suits my needs much better.

My next problem is why do they use a thick, inflexible cord with an end that sticks out twice as far from my laptop than the next one? Flexible is convenient, as is the end not sticking out 2 inches like a thumb drive.

I'm disappointed with this product because I purchased it for travel. For desktop use with an added extender cable it's fine, but it's too large for travel. I hope that I have helped you make your decision on this product, either way.

Works well so far. I have a portable USB hard drive, a printer and a mouse attached to it. Hard drive seems a bit slower than direct connection but it's just for backup so speed isn't that important to me.

This item came on time and was easy to install. It works just fine without any problems so far. With limited 3.0 USB Ports on the new Laptop Computers it is necessary to increase the ports to handle the additional devices. This one works for me.

The USB hub is great and works wonderful in my small area and large laptop. Shipping and handling and everything is great- thank you! I would recommend this device to anyone looking for something portable and that works like it's suppose to.

It seems like every device that I own needs to be plugged into a 5V USB port for either charging or data transfer. On some computers is not that big of a deal because I have plenty of USB ports, but on others, like my MacBook Pro, it can be a bit of a headache. The Bolse Bus-Powered 4 port USB Hub is nice because it is relatively small and does not require any additional power sources.

Notes-

- Bus-powered so while it will power most devices it does not have the ability to accept external power. Therefore, you probably will want to avoid charging devices (smartphones and tablets).

- Reverse compatible to USB 2.0, 1.1, and 1.0 devices

- All of the USB ports face up - making it easy to plug devices in. It may just be my personal preference, but I prefer top mount USB ports versus the more traditional side mount.

- Plug and play capable with my MacBook pro

- Good transfer speeds - I was routinely achieving 300-400mps while backing up my computer

Final verdict - The Bolse 4 Port USB Hub is a convenient way to add additional USB ports to your computer. It offers good transfer speeds, plug-and-play capability and reverse compatible to USB 2.0 and 1.1 devices.

After two cheap and nasty examples of this expired I treated myself to a quality example. There never seem to be enough usb ports on anything so that is the obvious primary usage.
I found it brilliant when connected to a usb mains adapter for charging usb battery charger for my camera, plus one of those spy pen cameras, plus one of those sunglasses spy cameras, plus my phone from a wall socket without having lots of items hanging off my laptop and using up all the usb ports.
If I had paid a bit more I would only have had to buy one instead of thre
